Potassium Acid Urate (CSH3KN4O3). This substance occurs only as a granular amorphous deposit. Owingto its greater solubility, it does not form as large an amount of the brick-dustdeposit as does the sodium salt. These two latter sediments are occasionally associated with amorphousdeposits of the calcium and magnesium acid urates. These are, however,rare and need not be separately considered. In detecting the presence of theurates in a deposit, a small portion of the turbid urine is poured into a test-tubeand gently heated. If urates are present the sediment will completely salts also give the murexid test. THE URINE. 341 (4). Xanthin (^O,). This substance which is chemically closely related to uric acid is rarelyfound as a sediment in the urine. Its chief cHnical importance is found inits appearance as a urinary calculus. It crystallizes in whetstone-shapedcolorless crystals which resemble those of uric acid, from which it is differ
